Economy of scale would be one of the most important issues among organizations pursuing system integration projects. Cerntainly there are other benefits than cost reduction for achieving system integration. However. these benefits could not be achieved automatically. if system integration projects were undertaken without thoughtful planning. In this paper. we propose a framework for an effective system integration by (1) defining the objects(user interface. database. application. and server) and (2) considering the level of integration(physical integration and rational integration). Therefore. 6 types of integration can be considered. Five case studies of domestic organizations were reviewed to suggest various issues and solutions. Based on our case studies. we discovered that five integration types - EIP. EAI. ERP. BPM and System Reconsolidation - were most widely used.

In this paper, we have proposed a methodology which can make effective test for system integration of complex guided missile system. System integration test play a significant role in the development of weapon system, providing the means to detect and isolate faults on first linkage between sub-systems. Integration tests for domestic weapon system has executed not a technology-intensive method based on tool but labor-intensive method based on experience. Higher cost, longer period, and more resource are required to execute system integration test for complex guided missile system comparing with past weapon systems, because recently weapon systems have more complex and more networked functions. Because the proposed design method for system integration test decreases number of test case, it lead to a decrease of cost, period, and resource for integration test of weapon system. The proposed configuration for system integration test will ensure reliability through detection and isolation of fault on linkage between sub-systems.

Purpose: This paper studied about the integration for management system of representative international standard related to sustainable development. The well-known International standards such as ISO 9001, ISO 14001 and OHSAS 18001 (ISO 45001) can be operated in accordance with the organizational situation individually, or in a variety of ways of integration. It can be applied to help organizations utilizing the newly established "ISO IEC Directive Part1 Annex SL", when integrating quality, environmental and safety & health management systems based on international standards. Methods: We conducted an empirical survey of management executives and experts to study how three factors (management systems, organizational capabilities and integration methods) could affect business performance. Results: The questionnaire was analyzed using AMOS structural equation model. Quality, environmental and safety and health management systems affected management performance, and integration methods of management system affected business efficiency, risk performance and financial performance. Integration method is also important because organizational competence affects various aspects of integrated management. However, factors that affect integration should also be considered in terms of organizational capabilities. This is because organizational capacity influences the integration plan. Conclusion: To integrate the document system at the strategic level, management should actively participate in integrated operations to integrate organizations, eliminate duplicate tasks, and foster document integration experts to reflect the characteristics of individual standard. In the case of document integration, quality management is focusing, but once ISO 45001 is issued, the use of Annex SL is increasing, and Quality, environment and safety & health integration will also be expanded. It is possible to increase the effect of integration by strategically approaching and establishing organization document system rather than simple integration according to management system standard arrangement.

The INS/GPS integration system is designed by employing an adaptive filter that can estimate the measurement noise variance using the residual of the filter. To verify the efficiency of the proposed loosely-coupled INS/GPS integration system, simulation is performed by assuming that GPS information has large position errors. Simulation results show that the proposed integration system with the adaptive filter is more effective in estimating the position and attitude errors than those with the Extended Kalman Filter.

This study proposes a construction plan for the Korea Navy's next-generation TSCE(Total Ship Computing Environment) based destroyers to address rapidly evolving maritime threats and decreasing military manpower. It focuses on system integrated ship construction based on TSCE for quick response time with fewer operators, improving the efficiency of systems and Equipments installed in the ship. The methodology includes analyzing TSCE-based system integration theories and levels. also analyze system integration in U.S. Navy's Zumwalt destroyers and Littoral Combat Ships, conducting expert surveys to build consensus on system integration methods, proposing operational efficiency improvements through TSCE-based system integration. Additionally, we propose an architecture of TSCE with real time OA(Open Architecture) from both functional and physical perspectives, verified through Python simulations. The study suggests optimal crew sizes for next-generation destroyers through comparative analysis of TSCE based integration types. It emphasizes the importance of system integration in naval ship construction, presenting specific measures to enhance operational efficiency and optimize crew operations. The findings are expected to contribute significantly to enhance the future naval capabilities of the Korea Navy.

In a centralized database system, all system components reside at a single platform. In recent years there has been a rapid trend toward the integration of information systems over multiple sites that are interconnected via a communication network, and users' needs are changed to integration of multiple information sites. Multi database System is one of solutions for integrating distributed heterogeneous databases. However the problems in multi database system are restriction in distributed environment support, limitation in integrating heterogeneous media type data, static integration, and data-only of integration. In order to solve these problems, we propose a hybrid database integration model, HyDIM. HyDIM is used for the integrating legacy multimedia data, adopting CORBA, MDS, and mediator. We demonstrate a prototype system far PDM application domain.

This paper compare with SNR performance of coherent integration and non-coherent integration in radar system. This paper to prevent distortion of transmit signal and radar return in radar system is used to pulsed waveform. This paper to estimate target detection range and to compare with SNR performance used to coherent integration performed before the envelope detector and non-coherent integration processed after the envelope detector. Through simulation, SNR performance of coherent integration and non-coherent integration were comparatively analyzed. SNR performance of coherent integration is good proof higher than non-coherent integration.

In the large and multifunctional engineering system, the heterogeneous computer system situation is inevitable. Accordingly a lot of integration efforts are being made to comply with the industrial requirement of productivity. In this paper, a practical concept of integration is introduced through the development of a prototype system for ship outfitting design which is a typical example of large/multi-functional application system. On the development of the prototype system, three points are considered as a practical concept-which are integration of database, integration of application programs, and system-user interface. The relation model based commercial database management system(RDBMS) is used to build the project integrated database, and the graphical user interface tool(OSF/Motif) on X-window system is used for the integration of application programs and the user interface.

In this paper, we analysed a performance signal to noise ratio about pulse, integration coherent, and integration non coherent system in radar system. It compared existing with proposal method in order to estimation two target direction of arrival. Generally, radar system radiate pulse wave in order to decreasing distortion of return wave and transmission wave. We analysed the performance integration coherent and integration non coherent. Integration coherent is processing system before doing envelop detection, and integration non coherent is processing system after doing envelop detection. Through simulation, we analysed a performance signal to noise ratio to estimation two target range detection and estimated target direction of arrival. We showed that integration coherent system is the most good performance.
